+
+      "Derivative Works" shall mean any work, whether in Source or Object

+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,

+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+# undo
+
+A clean, robust, and easy-to-use Undo/Redo library for Dart and Flutter. It leverages the Command Pattern to manage state changes, allowing you to easily roll back or replay actions in your application.
+
+## Features
+
+*   🔄 **Undo/Redo**: Simple stack-based undo/redo history.
+*   📦 **Batched Changes**: Group multiple changes into a single undoable action (e.g., a multi-field form update).
+*   🎨 **Flexible**: Works with any architecture (ChangeNotifier, Bloc, Riverpod, etc.).
+*   ⚡ **Lightweight**: Minimal overhead, zero dependencies.
+
+## Installation
+
+Add dependencies to your `pubspec.yaml`:
+
+```yaml
+dependencies:
+  undo: ^1.6.0
+```
+
+Run `pub get` or `flutter pub get`.
+
+## Usage
+
+### Basic Usage
+
+Create a `ChangeStack` to manage your changes. A `Change` consists of:
+1.  The **old state** (to revert to).
+2.  The **execute** logic (to perform the change).
+3.  The **undo** logic (to revert the change).
+
+```dart
+import 'package:undo/undo.dart';
+
+void main() {
+  final changes = ChangeStack();
+  var count = 0;
+
+  // Perform a change
+  changes.add(
+    Change<int>(
+      count, // Old value (0)
+      () => count++, // Execute: increment
+      (oldVal) => count = oldVal, // Undo: set back to old val
+      description: 'Increment count',
+    ),
+  );
+
+  print(count); // 1
+
+  // Undo the change
+  changes.undo();
+  print(count); // 0
+  
+  // Redo the change
+  changes.redo();
+  print(count); // 1
+}
+```
+
+### Working with Objects
+
+When modifying objects, capture the specific field value *before* the change so you can restore it.
+
+```dart
+class User {
+  String name = 'John';
+}
+
+void main() {
+  final user = User();
+  final changes = ChangeStack();
+
+  // Capture the OLD name before changing it
+  final oldName = user.name;
+
+  changes.add(
+    Change<String>(
+      oldName,
+      () => user.name = 'Jane', // New name
+      (val) => user.name = val, // Restore old name
+      description: 'Update name',
+    ),
+  );
+  
+  print(user.name); // Jane
+  changes.undo();
+  print(user.name); // John
+}
+```
+
+### SimpleStack (Quick Start)
+
+`SimpleStack` is a wrapper around `ChangeStack` that makes it easier to track a single state object. It's great for simple use cases.
+
+```dart
+final stack = SimpleStack<int>(0); // Initial state is 0
+
+// Modifying state automatically creates a change history
+stack.modify(1); 
+print(stack.state); // 1
+
+stack.undo();
+print(stack.state); // 0
+```
+
+### Grouping Changes
+
+Sometimes you want multiple operations to be undone as a single step. Use `addGroup` (or manual `group` logic in 1.6.0+).
+
+```dart
+changes.add(
+  Change.group([
+    Change(
+      user.firstName,
+      () => user.firstName = 'Jane',
+      (val) => user.firstName = val,
+    ),
+    Change(
+      user.lastName,
+      () => user.lastName = 'Doe',
+      (val) => user.lastName = val,
+    ),
+  ]),
+);
+```
+
+## Flutter Integration
+
+`ChangeStack` works seamlessly with `ChangeNotifier` to rebuild your UI when undo/redo state changes.
+
+```dart
+class MyController extends ChangeNotifier {
+  final ChangeStack _changes = ChangeStack();
+  int _count = 0;
+
+  int get count => _count;
+  bool get canUndo => _changes.canUndo;
+  bool get canRedo => _changes.canRedo;
+
+  void increment() {
+    _changes.add(
+      Change<int>(
+        _count,
+        () {
+           _count++;
+           notifyListeners();
+        },
+        (oldVal) {
+           _count = oldVal;
+           notifyListeners();
+        },
+      ),
+    );
+  }
+
+  void undo() {
+    _changes.undo();
+    notifyListeners();
+  }
+
+  void redo() {
+    _changes.redo();
+    notifyListeners();
+  }
+}
+```
